Parallel Port Interrupt

The parallel port can be configured to generate an interrupt request upon a variety of conditions. In
most applications, the interrupt is not used. The standard parallel port interrupts are IRQ7 for the
primary port and IRQ5 for the secondary port. The IRQ channel assignments are standard and
cannot be changed. A bit in the parallel port's command registers enables or disables the port’s
connection to its interrupt line.
